HYDROCARBON-BURNER.

SPECIFICATION forming' part Of Letters Patent N0. 683,134, dated September 24, 1901. Application filed October 31, 1900. Serial No. 35,058. (No model.)

To @ZZ whom t may concern.-

Be it known that I, JAMES A. MASON, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I do hereby declare the .following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hydrocarbon-burners, and more particularly to such as are adapted for use as a furnace in locomobiles, one object of the invention being to provide an extended surface or passage for oil while being subjected to heat for vaporizing the same, so that all the oil will be thoroughly vaporized, and thus prevent the escape of any oil with the vapor.

A further object is lto provide simple and efficient means for straining the Vapor and also the oil and at the same time preventing clogging in said strainer.

A further object is to provide a hydrocarbon-burner which shall be simple in construction, comprise few parts, which can be mann factured at a comparatively small cost, and which shall be effectual in the performance of its functions.

With these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanyingdrawings, Figure lisa sectional view through twin burners embodying my invention. Fig. 2 is a transverse sectional view on the line a: of Fig. 1. Fig. 3 is a View on the line y y of Fig. 1. Fig. ft is a detail view of the self-cleaning strainer.

1 represents a retort, comprisingr a casting having a serpentine passage 2 therein to afford an extended area for the oil during the vaporization thereof. One end of the casting 1 of the retort is provided with an opening 3 for the removal of the core, which forms the serpentine passage, and this opening is closed by a plug 4t. The retort is provided at one end with a dome G, with which one end of the serpentine passage communicates to convey vapor thereto, and this dome communicates with a duct 7, made in a depending leg or casting 8. At its lower end the duct 7 communicates Witha curved pipe 9, which terminates below the retort 1 for the reception 55 of a burner 10 of any preferred form of construction, and this burner is provided with a starting-cup l1. The depending leg or casting Sis also made with a channel 12. The core by means of which this channel is formed can be 6o readily removed through an opening 13 in the bottom ofthe dome, which opening is closed by means of a plug 14. The core by Which the Vapor-chamber in the dome is formed :can

be removed through an opening 15, and this opening is'closed by a plug 16. The openings 13 and 15 also serve another purpose-viz., to permit the assembling of the parts. The oil-pipe 17 is passed through the channel 12,

through the opening 13, through the dome, l7o

and out through the opening 15. A collar 18 is then screwed on the upper end of the pipe 17, and then a self-cleaning strainer 2O is screwed on the end of said pipe. The pipe is then drawn back through the dome and bent over, so as to cause the end ofthe strainer to enter one end of the serpentine passage 2 of the retort 1, after which the collar 18 is screwed up against the shoulder 21n on the retort, as shown in Fig. 1. The plug 14 8e is then placed in position to effectually close the opening 13. A self-cleaning strainer 21 is placed loosely in the upper end of the vaporduct 7, and the opening 15 serves as a ready means for permitting the insertion of said strainer. After the strainer 2l shall have been placed into position the opening 15 will be permanently closed by the plug 16. The self-cleaning strainer 2l comprises a shell 22,

provided with a conical end portion which 9o projects into the duct 7, and a smaller shell 23, disposed within and spaced from the shell 22, said shell 23 also having a depending conical portion 2t. The shell 22 is provided with a hood 25, having a closed top and proslots or openings 27, and the conical lower roo end 24 is also made with slots or openings 28 to facilitate the passage of vapor. Shot 29 is placed in the shell 23 suflicient to partially ll the same, and shot 30 is also placed in the space between the shells 22 and 23, so as to only partially ill said space. From this construction and arrangement of parts it will be seen that the vapor will be properly strained as it enters the vapor-duct 7 and that the strainer will be eectually prevented from clogging,because the vibration of the vehicle (locomobile).will cause a constant agitation of the shot, which will result in removing any sediment which might take place in the strainer. The strainer 2O between the oilpipe and the retort is the same in construction as the strainer 21, with the exception of the hood, (which is omitted from the strainer 20,) and lhereforea detail description of the oil-strainer would be a mere repetition of the above description of the strainer 21.

In the drawings I have shown two burners lnade in a single casting; but they are identical in construction and a description of one will sui'iice for both. In Fig. 1 the section is so taken through the twin burners that the oil-inlet to the retort is shown in one and the vapor-outlet from the retort to the dome is shown in the other.

Having fully described my invention, what I'cl'aim as new, and desire to secure by Letters Patent, is

"1. In a hydrocarbon-burner, the combination of a retort, a dome integral with said retort and communicating with one end thereof, a leg depending from the retort and having a vapor-duct communicating with the dome, an oil-pipe passing through said leg and communicating with the retort and a burner communicating with the vapor-duct for heat-ing the retort.

2. In a hydrocarbon-buruer, the combination of a retort, a burner for heating the same, a duct for conveying vapor to thel burner, a self-cleaning strainer in the inlet end of said duct, an oil-pipe communicating with the retort and a selfoleaning strainer on the outlet Yend of said oil-pipe, each of said self-cleaning strainers comprising a shell partially filled with movable particles.

3. In a hydrocarbon-burner, the combination with a retort, means for feeding oil thereto, a burner and means for feeding vapor from the retort to the burner, of aselfcleaning strainer comprising shells one Within the other and spaced apart, the inner shell having slots and movable particles partially lling the shells.

4. Astrainerforahydrocarbon-burnercomprising concentric shells spaced apart, the inner shell having slots, shot partiallyr filling the space within the inner shell and shot partially filling the space between said shells.

5. Astrainerforahydrocarbon-burnercomprising concentric shells spaced apart and having conical lower ends, the inner shell having openings in its Wall and shot partially lling said shells.

6. Astrainerforahydrocarbon-burnerconiprising concentric shells spaced apart, the inner shell having openings in its Wall, shot partially filling said shells, and a cap on said shells having a closed top and openings in its side wall.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
